The Workers’ Compensation Appeals Tribunal (WCAT), under the legislative authority of the WorkplaceHealth, Safety and Compensation Commission and Workers’ Compensation Appeals Tribunal Act is mandated to hear appeals under this Act, the Workers' Compensation Act, the Firefighters' Compensation Act and the Occupational Health and Safety Act.

Independent from the Workplace Health, Safety and Compensation Commission or WorkSafeNB, the WCAT is a quasi-judicial administrative tribunal. If workers, their dependents or employers are dissatisfied with a decision made by WorkSafeNB, they can appeal the decision to the WCAT.
